Singh,Nobody really rides these things at 100mph anyway.Realistically a top speed of 85-90mph is fine, and most people would cruise around 70mph anyway, so "the Ton" is really just a "benchmark" so you can say that you have accomplished it.

It was of interest to me, because I was the engine designer, and so I wanted to hit my goals. I think the only Fireball rider who has even tried to come near "the Ton" has been Chumma, and he did it alot. Especially during the testing when we were trying to make it get over "the Ton". He did 99mph alot of times along the way too, when we were trying to get it over the magic mark.

Gearing? I'm writing this from memory without referring back to facts but I think that the G5 gearing could be raised to about 90mph tops going one tooth up on the front sprocket.

I have almost certainly decided though that I will fit a Power Commander and K&N, (already have the open pipe) and raise the gearing once the bike is out of warranty. A real 90mph will probably show a ton on the clock and that's enough for me!

@Clubman - Good idea to change the front sprocket to one tooth up and it will be close to 90 mph ! Is there a power commander available in UK for RE EFI models ? When you do get it, let us know how does it perform on your bike as you reach the limit of your speedo or otherwise.

Ace, yes! The ton is just a limit that most people would probably hit once if at all BUT the added torque and power for better acceleration and the ability to easily cruise at 70-75mph is what most people are really after. Still, with bikes that look right for the era it just sounds wimpy if you can't hit the ton
